28 C.F.R. § 36.208 Direct threat.
Title 28 - Judicial Administration
(a) This part does not require a public accommodation to permit an individual to participate in or benefit from the goods, services, facilities, privileges, advantages and accommodations of that public accommodation when that individual poses a direct threat to the health or safety of others. (b) Direct threat means a significant risk to the health or safety of others that cannot be eliminated by a modification of policies, practices, or procedures, or by the provision of auxiliary aids or services. (c) In determining whether an individual poses a direct threat to the health or safety of others, a public accommodation must make an individualized assessment, based on reasonable judgment that relies on current medical knowledge or on the best available objective evidence, to ascertain: the nature, duration, and severity of the risk; the probability that the potential injury will actually occur; and whether reasonable modifications of policies, practices, or procedures will mitigate the risk.
